Note that these triggers are typically generated for several types of changes to the file system, including adding a file, deleting a file, modifying a file, etc.
- FAM File Alteration Monitor
- the File System process ends at step 208 .
- Content Detector process 210 initializes at step 212 by reading the file directory of the file system to obtain a reference file list. As file system event triggers are received at event queue 214 , the Content Detector process is triggered to read the file directory at step 216 to get a new file list. At step 218 , the reference file list and the new file list are compared to determine if a new file has been received in which case, at step 222 the file name of the new file is retrieved. Note that if multiple files are new, the system will perform the following steps on each of the new files.

At step 226 the system determines if the new file is ready to be used.
- the system determines if the file is closed as an indication that the file is not currently being altered or written to. In some embodiments the system can retrieve the file size, wait a predetermined period of time, for example one second, and retrieve the file size again to determine if the file size is stable which can help ensure that the file is not being written to sporadically, between periods of being closed. If the file is not ready step 226 is repeated until the file is ready. Once the new file is ready to be read, the Content Detector process initiates the Content Processor process 227 .
- the Content Processor process 227 starts at step 228 the Content Processor process opens the new file and at step 230 determines the file type by reading the file extension.
- the file type is determined by analyzing the file header format.
- Supported multimedia file types include but are not limited to: image files such as JPEG (Joint Photographic Experts Group) and Raw (camera raw image file); audio files such as WAV (Waveform Audio file format) and MP3 (Moving Picture Experts Group (MPEG)-1 or MPEG-2, Audio Layer 3); or video files such as MOV (QuickTime or MP4 (MPEG-4)).
- the process is directed to WAV routine 232 and at step 242 the WAV audio file is encoded/compressed to MP3 audio file format and then at step 244 a description of the file is automatically generated from available and parsed metadata and other data associated with the file.
- Metadata can include picture date/time, camera model and manufacturer, exposure time/mode/program, F-number, ISO speed, focal length, flash on/off, white balance mode, size, author/photographer name, copyright information, GPS location, etc.
- Other data can include a location address or label derived from reverse geocoding GPS coordinates, or derived from a database look up of a subscriber name or user ID associated with the FTP client of camera 102 or LTE radio interface adapter 104 .
- the user ID can be correlated with user information pre-populated on database 114 , including user name, address and other information.
- the new file is added to database 114 . Once loaded on the database, the file is available to subscribers or authorized users of multi-media application server 112 , using conventional file server techniques well known to persons of skill in the art.
- the process sends notification to a pre-registered contact list, advising that a new multimedia file is available.
- the contact list can include one or more email addresses, another machine(s), or another application(s) accessible through the Internet (“The cloud”) 110 .
- Notification can take the form of an email, text message, or other electronic message format. In this manner, notification could be sent to a news editor awaiting breaking news photos from a photographer or to a subscriber awaiting multimedia files matching specific search criteria such as a key word in the description, a specific photographer, a specific location, etc., of the file added to database 114 .
- the process sends the processed file itself to the pre-registered contact list. If at step 230 , the new file is determined to be an MP3 audio file, the process is directed to MP3 routine 234 which proceeds directly to step 244 as described previously.
- the process is directed to RAW routine 236 .
- the process parses the metadata of the image file which is used in later steps.
- the metadata can include picture date/time, camera model and manufacturer, exposure time/mode/program, F-number, ISO speed, focal length, flash on/off, white balance mode, size, author/photographer name, copyright information, GPS location, etc.

- the location address is then retrieved from the mapping utility.
- Some mapping utilities can also retrieve a label or name for well-known landmarks at a specific location or address. If available, such a label is also retrieved.
- the process then continues to step 244 where the parsed metadata, retrieved location address is used to automatically generate a description of the file as described previously.
- the Raw image file is also encoded/compressed to JPEG image format at step 254 .
- the process then follows the JPG routine 238 at step 258 , described below.
- the process is directed to JPG routine 238 which starts at step 258 where the process parses the metadata of the image file which is used in later steps.
- the metadata can include picture date/time, camera model and manufacturer, exposure time/mode/program, F-number, ISO speed, focal length, flash on/off, white balance mode, size, author/photographer name, copyright information, GPS location, etc.

- the overlay watermark could be a logo or a copyright notice for marketing purposes or to prevent or discourage unauthorized copying of the image if it will be made widely available such as by publishing on a public website.
- a thumbnail image is generated.
- a thumbnail image is a greatly reduced image size having a commensurately reduced file size useful as an index image and suitable for displaying multiple images on a user interface such as a display on a mobile telephone, a computer display, or other user display.
- an embedded EXIF (Exchangeable image file format) thumbnail image is extracted from the metadata of the JPEG image file.
- a preview image is generated.
- a preview image is a reduced size image having a reduced file size, optimized for viewing on a user interface.
- step 246 when the new file is added to database 114 , the thumbnail image file generated at step 264 and the preview image file generated at step 266 are also added to database 114 .
- the thumbnail image file is stored in a separate thumbnail directory and the preview image file is stored in a separate preview image directory.
- the process is directed to MOV routine 240 .
- a thumbnail image representative of the video file is generated.
- the first frame of the video file is captured and converted to a thumbnail-size JPEG image file.
- a preview image corresponding to the thumbnail image is generated. The thumbnail image generated at step 268 and the preview image generated at step 270 , are useful for representing the video file to a user when displayed in a directory listing context. The process then continues to step 244 as described previously.
- Advantages of the present invention can include speed of processing multimedia files and especially in the case of multiple multi-media files, the consequent high volume capability (automatically and without human intervention). This becomes even more important with the introduction of LTE and other high speed and high bandwidth mobile communications systems and the inevitable increase in number of resolution still image and video cameras with built-in high speed communication capability.
- Other advantages may include improved accuracy of receipt-time logging of photos and multimedia files because they are processed on an interrupt-driven basis, thus processed quickly and with delays related to human intervention and because of the uniformity of processing operation for a given user profile and file type.

Abstract
Description
- The invention is directed to wireless data communication systems, and in particular to a system for automated access to photos and video.
- Today, professional photographers and others such as first responders, insurance adjusters, real estate agents, and other professionals who use professional-grade photographic equipment to capture information, evidence, or commercial images are limited in their ability to transfer photos, video, and metadata quickly from remote locations. The transfer of such data typically requires a WiFi zone or a fixed broadband connection, the access to which may be some distance from the scene of the photograph. This limitation costs the photographer time and money.
- In addition, professional tools for processing images and video, workflow management, and publication of digital media are often limited to software applications that run on laptops used by individual photographers or on workstations with locally installed or client/server-based applications that are available only from the publishing office Local Area Network (LAN). The support of such infrastructure is expensive and inefficient—especially if there is a large pool of users in the field, or if the data requires complex, multi-site processing.
- Therefore, a means for automatically receiving and processing images, video and audio would be highly desirable.
- One aspect of an embodiment of the present invention provides a method of automatically processing multimedia files in a cloud-based multi-media application server. The method comprises steps of: receiving at the application server, a multi-media file; responsive to the receiving step, processing the multi-media file; storing the processed multi-media file in a database for access by authorized users of the application server, wherein the processing comprises parsing metadata embedded in the multimedia file.

- In some embodiments of the invention the receiving step further comprises capturing a user ID (identifier) associated with the multi-media file.
- In some embodiments of the invention the step of processing the multi-media file comprises reverse geocoding location coordinates to a location label.
- In some embodiments of the invention the location label comprises a street address.
- In some embodiments of the invention the step of processing comprises a step of automatically generating a description from metadata parsed from the multi-media file.
- In some embodiments of the invention the step of generating a description further comprises using a user ID (identifier) associated with the multi-media file.
- In some embodiments of the invention the step of generating a description further comprises incorporating user information pre-populated on a database correlated with the user ID.
- Some embodiments of the invention further comprise a step of sending a notification to a pre-registered contact list.
- In some embodiments of the invention the notification comprises a copy of the multimedia file.
- Some embodiments of the invention further comprise a step of generating a thumbnail image from an image or video frame if available, of the multi-media file.
- Some embodiments of the invention further comprise a step of storing the thumbnail image in the database.
- In some embodiments of the invention the multi-media file has a format selected from one of the following types: JPEG (Joint Photographic Experts Group) image file; Raw (camera raw image file); WAV (Waveform Audio file format) audio file MP3 (Moving Picture Experts Group (MPEG)-1 or MPEG-2, Audio Layer 3) audio file; and MOV (QuickTime or MP4 (MPEG-4)) video.
- In some embodiments of the invention the processed multi-media file comprises a JPEG (Joint Photographic Experts Group) image file, then overlaying a predefined overlay watermark to the image file.
- Another aspect of an embodiment of the present invention provides an automated cloud-hosted multi-media application server comprising; a file system for receiving and managing files; a content detector for detecting multi-media files received by the file system; and a content processor responsive to the content detector for automatically processing the multi-media files and storing the multi-media files in a database for access by authorized users of the application server, wherein the processing comprises parsing metadata embedded in the multimedia file.

The system determines if the file is closed as an indication that the file is not currently being altered or written to. In some embodiments the system can retrieve the file size, wait a predetermined period of time, for example one second, and retrieve the file size again to determine if the file size is stable which can help ensure that the file is not being written to sporadically, between periods of being closed. If the file is notready step 226 is repeated until the file is ready. Once the new file is ready to be read, the Content Detector process initiates theContent Processor process 227. - The
Content Processor process 227 starts atstep 228 the Content Processor process opens the new file and atstep 230 determines the file type by reading the file extension. In some embodiments the file type is determined by analyzing the file header format.

step 230, the new file is determined to be a WAV audio file, the process is directed toWAV routine 232 and atstep 242 the WAV audio file is encoded/compressed to MP3 audio file format and then at step 244 a description of the file is automatically generated from available and parsed metadata and other data associated with the file. Metadata can include picture date/time, camera model and manufacturer, exposure time/mode/program, F-number, ISO speed, focal length, flash on/off, white balance mode, size, author/photographer name, copyright information, GPS location, etc. Other data can include a location address or label derived from reverse geocoding GPS coordinates, or derived from a database look up of a subscriber name or user ID associated with the FTP client ofcamera 102 or LTEradio interface adapter 104. The user ID can be correlated with user information pre-populated ondatabase 114, including user name, address and other information. Atstep 246 the new file is added todatabase 114. Once loaded on the database, the file is available to subscribers or authorized users ofmulti-media application server 112, using conventional file server techniques well known to persons of skill in the art. In some embodiments, atstep 246, the process sends notification to a pre-registered contact list, advising that a new multimedia file is available. The contact list can include one or more email addresses, another machine(s), or another application(s) accessible through the Internet (“The cloud”) 110. Notification can take the form of an email, text message, or other electronic message format. In this manner, notification could be sent to a news editor awaiting breaking news photos from a photographer or to a subscriber awaiting multimedia files matching specific search criteria such as a key word in the description, a specific photographer, a specific location, etc., of the file added todatabase 114. - In other embodiments, at
step 248, the process sends the processed file itself to the pre-registered contact list. If atstep 230, the new file is determined to be an MP3 audio file, the process is directed toMP3 routine 234 which proceeds directly to step 244 as described previously. - If at
step 230, the new file is determined to be a Raw image file, the process is directed toRAW routine 236. Atstep 250 the process parses the metadata of the image file which is used in later steps. The metadata can include picture date/time, camera model and manufacturer, exposure time/mode/program, F-number, ISO speed, focal length, flash on/off, white balance mode, size, author/photographer name, copyright information, GPS location, etc. Atstep 252, the process reverse geocodes the location information parsed from the image file as GPS latitude and longitude coordinates. In one embodiment, the GPS latitude and longitude coordinates are transmitted to a mapping utility such as for example, Google maps (maps.google.com), operated by Google Inc. The location address is then retrieved from the mapping utility. Some mapping utilities can also retrieve a label or name for well-known landmarks at a specific location or address. If available, such a label is also retrieved. The process then continues to step 244 where the parsed metadata, retrieved location address is used to automatically generate a description of the file as described previously. In some embodiments, the Raw image file is also encoded/compressed to JPEG image format atstep 254. The process then follows the JPG routine 238 atstep 258, described below. - If at
step 230, the new file is determined to be a JPEG image file, the process is directed to JPG routine 238 which starts atstep 258 where the process parses the metadata of the image file which is used in later steps. The metadata can include picture date/time, camera model and manufacturer, exposure time/mode/program, F-number, ISO speed, focal length, flash on/off, white balance mode, size, author/photographer name, copyright information, GPS location, etc. Atstep 260, the process reverse geocodes the location information parsed from the image file as GPS latitude and longitude coordinates as described instep 252. Atstep 262, a predefined overlay watermark is applied to the JPEG image. The overlay watermark could be a logo or a copyright notice for marketing purposes or to prevent or discourage unauthorized copying of the image if it will be made widely available such as by publishing on a public website. At step 264 a thumbnail image is generated. A thumbnail image is a greatly reduced image size having a commensurately reduced file size useful as an index image and suitable for displaying multiple images on a user interface such as a display on a mobile telephone, a computer display, or other user display. In some embodiments, an embedded EXIF (Exchangeable image file format) thumbnail image is extracted from the metadata of the JPEG image file. At step 266 a preview image is generated. A preview image is a reduced size image having a reduced file size, optimized for viewing on a user interface. The process then continues to step 244 described previously. Note that atstep 246, when the new file is added todatabase 114, the thumbnail image file generated atstep 264 and the preview image file generated atstep 266 are also added todatabase 114. In some embodiments, the thumbnail image file is stored in a separate thumbnail directory and the preview image file is stored in a separate preview image directory. - If at
step 230, the new file is determined to be a MOV video file, the process is directed toMOV routine 240. Atstep 268, a thumbnail image representative of the video file is generated. In some embodiments, the first frame of the video file is captured and converted to a thumbnail-size JPEG image file. Atstep 270, a preview image corresponding to the thumbnail image is generated. The thumbnail image generated atstep 268 and the preview image generated atstep 270, are useful for representing the video file to a user when displayed in a directory listing context. The process then continues to step 244 as described previously. - Advantages of the present invention can include speed of processing multimedia files and especially in the case of multiple multi-media files, the consequent high volume capability (automatically and without human intervention). This becomes even more important with the introduction of LTE and other high speed and high bandwidth mobile communications systems and the inevitable increase in number of resolution still image and video cameras with built-in high speed communication capability. Other advantages may include improved accuracy of receipt-time logging of photos and multimedia files because they are processed on an interrupt-driven basis, thus processed quickly and with delays related to human intervention and because of the uniformity of processing operation for a given user profile and file type. The advantages of the cloud-based location of the application server relieves users from maintaining a computer and related software and performing repetitious workflow actions on multi-media files to make them available to clients, editors, other users, social networking services, etc.
